virtual double Evaluate(double t)=0
Interpolate the value of the spline at parametric location of t.
computes an interpolating spline using a Kochanek basis.

void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual void DeepCopy(vtkSpline *s)
Deep copy of spline data.
virtual void Compute()=0
Compute the coefficients for the spline.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
